changing 2013 50hp efi 4stk to 60hp efi 4stk

[mustangdt]

would like to know if anyone could help with what is required to change a 2013 mercury 50hp efi 4stk to a 60hp efi 4stk. I see the engine is the same internally so it must be ecu, injectors, throttle body etc. any help would be appreciated.

Ecm and the possible restrictor in the throttle body.
